Cosmologists Find Eleven Runaway Galaxies

An anonymous reader writes: Discovery News reports that 11 homeless galaxies have been identified by Igor Chilingarian, an astronomer at the Harvard-Smithsonian Center for Astrophysics, and Moscow State University, and his fellow astronomers. "The 11 runaway galaxies were found by chance while Chilingarian and co-investigator Ivan Zolotukhin, of the L'Institut de Recherche en Astrophysique et Planetologie and Moscow State University, were scouring publicly-available data (via the Virtual Observatory) from the Sloan Digital Sky Survey and the GALEX satellite for compact elliptical galaxies."

      The answer to that would be, 'er', yes. It indicates that astronomical motions are for more chaotic than imagined and hence as you go down from large to small so that chaos would reflect in more errant objects. So yeah, we can quite readily be impacted by dangerous objects at any time and it behoves us to try to do something about reducing risk, the smaller the objects the more prevalent they and the greater the risk of impact. So finding high risk objects and reducing that risk. It's like the the stupid, why study volcanoes can not do nothing to stop them, what a waste of time. The reason of course to study volcanoes is to figure out when they will erupt and ensure harm to people and property is minimised.

    One of the things that always bothered me about this is the ambiguity of the approximation as well. Two interpretations:

    More than a ratio of 0.0005 but less than a ratio of 0.0015, suggests 667-2000 times.

    How much overlap is there between these two ranges? 55.5% (667-1500) of the total range (500-2000) is overlap. The same is true for writing it as ratios: the range from 0.00067-0.00150 is 55.5% of 0.0005-0.0020.

    This is tangentially related to why getting 40% off from someone charging 50% over MSRP is better than buying at MSRP. Without thinking about it, one might expect to spend 10% more in the first case (50% - 40% = 10%), but they're actually saving 10% instead (1.5 * 0.6 = 0.9).

    When someone says, "The new battery is ten times smaller than the old battery," yes ... we can guess that part of what's meant is, "The new battery is a tenth the size of the old battery."

    Except you're not guessing. There is no confusion that it might mean something else. You've seen this pattern dozens, if not hundreds of times before, and it always means the same thing.

    The reason we have lots of vocabulary words, adjectives, and constructions is so that we can be nuanced and more precise in simple communication.

    Yes, English has many nuanced words, but smaller is not one of them. It means comparatively small. It is one of the more basic and common words, and has a simple meaning.

    you're communicating that the old battery is small,

    No, you're not. It is perfectly reasonable for someone to say something like, "The Small Magellanic Cloud is the smaller of the two Magellanic Clouds," without implying it is smaller than a breadbox or even small in general.

    It's no different than people who say, "I could care less," when they mean exactly the opposite

    It is very different from that phrase. That phrase has a literal meaning exactly opposite the intended meaning. The phrase "ten times smaller" doesn't have multiple interpretations (unless contorting things as GP said). Even if we ignore that, and take your meaning that it implies both items are small for some reason, that is still not the opposite of saying one is not as large as the other.

    Fine, you don't like the wording. But you're trying pretty hard to post hoc rationalize a justification instead of just admitting you don't like it... then you run with it and project what that must about people who don't share your dislike.

    OK. But let's say you don't know how big the Small Magellanic Cloud is, relative to, say, the Milky Way, or Andromeda, or anything else.

    No, I don't like people conveying information in a way that forces you to go research something they mentioned without providing any useful context. When somebody cites a comparative size, but doesn't explain why (or if) that comparison is meaningful, then it's a waste of time.

    It's a shame that your own literacy is so limited, and that your own ability to parse the differences between words is disabled by a lack of vocabulary breadth. That's got to be frustrating. Or maybe not, since perhaps ignorance is bliss in some way, right?

    Saying that something is "ten times smaller" is like saying "ten times more small." The phrase "ten times" is a multiplier. It means that you're describing an aspect of something, and saying that there is ten times as much of that aspect. In that usage, the aspect you're describing and comparing is the smallness.

    By choosing that construction ("A is ten times smaller than B"), you're deliberately focusing on B's size, and implying that the smallness of B is the thing that's being multiplied ... that B's smallness is important in what you're communicating, and that it's of note because A's size is even more so (small, that is). If we're not trying to convey B's smallness as part of the concept being communicated (perhaps B isn't really thought of as small at all, in the scheme of things), a different construction makes more sense. Makes for better communication: "A is tenth of B's size." We're still describing the relationship, but doing so without including words that suggest B's size is already considered small.

    That you don't have the cognitive and communication skills to understand the difference, or that you DO, and prefer to have communication dumbed down and muddied, and require more back and forth to clarify what you mean, says a lot about you. Which is unfortunate. That you think you have to insult someone else in order to feel better about it is just kind of pathetic, really.

    No, no constraints in that sense. Just the larger constraints introduced by the fact that the purpose of saying anything at all, in that context, is to communicate something meaningful about A's size. And by choosing the "ten times more" construction, part of what you're communicating is the fact that B, the thing to which you're comparing A, is by implication already considered small. That format (rather than saying, "A is a tenth B's size") is a choice of words that communicates the understand that B is small, and A is even more small. The phrase "ten times smaller" is using the word "smaller" in the sense of "more small."

    The words "ten times" is a multiplier. It's used, in a comparison, to say that one value is LARGER than another. In this usage, the smallness of A is ten times larger than the smallness of B. Trotting out that multiplier is a deliberate choice made to focus on smallness in both A and B, with A having ten times more of it. That doesn't describe the size of B, but it communicates that notion that B is already - in the scheme of things - considered small, and A more so.
